Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 7,000 years ago 1111111111111 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332162742 2019-02-17 20:36:45 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332162742 191482 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332162966 There is more carbon dioxide in the atmosphere today than at any point in the last 800,000 years.

That might not seem like a lot, but the average temperature during the last Ice Age was about 4º F lower than it is today. 190968 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332163124 2019-02-17 20:39:45 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332163124 1904213 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332163174 2019-02-17 20:40:06 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332163174 191482 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332163289 The global warming that has occurred since the 1970s caused over 140,000 excess deaths annually by the year 2004.]]> 2019-02-17 20:40:59 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332163289 1904213 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332163367 Global Warming has made Antarctica Melt and that means the sea levels are rising]]> 2019-02-17 20:41:33 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332163367 Global warming is a long-term rise in the average temperature of the Earth's climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming. 1111111111111 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332164274 2019-02-17 20:48:18 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332164274 Since 1978, a series of satellite instruments have measured the energy output of the Sun directly. The satellite data show a very slight drop in solar irradiance (which is a measure of the amount of energy the Sun gives off) over this time period. So the Sun doesn't appear to be responsible for the warming trend observed over the past several decades. 190968 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332164441 2019-02-17 20:49:31 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332164441 Earth's global surface temperature in 2018 was the fourth warmest since 1880, 1111111111111 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332164486 2019-02-17 20:49:49 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332164486 The Arctic Ocean's sea ice blanket has already lost most of its old ice and two-thirds of its thickness.

The Greenland and Antarctic ice sheets have decreased in mass. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost an average of 281 billion tons of ice per year between 1993 and 2016, while Antarctica lost about 119 billion tons during the same time period. The rate of Antarctica ice mass loss has tripled in the last decade.]]> 2019-02-18 23:35:15 UTC https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332487069 What Don't we Like about Global warming? 1904213 https://padlet.com/1904213/SocialStudiesPBL_Reee_Oof/wish/332487327  It's too hot and it is hard to focus in the heat.

Even a seemingly slight average temperature rise is enough to cause a dramatic transformation of our planet.
